A collection of Networking Study Material

This collection of study guides, papers, movies, videos, presentations, tables, calculators, posters, questions & answers, etc. are meant to be used by those preparing to write the Cisco CCNA exam, as well as IT professionals looking to learn more about networking concepts, and Cisco routing and switching.

There is no substitution for knowledge and understanding. Cisco has protected it's certifications by requiring that you KNOW and UNDERSTAND networking. Memorizing answers to questions will not give you the skills for you to get a job or keep a job.

About sources
This is a collection from various text, internet sites, and my own writings I have collected over the years. A lot of the material in these Study Guides is a collection of the work of others. They are by no means all mine. It is not my intention to duplicate for my gain the work of others without giving them credit. The problem is I have not kept, nor could I possibly find, the true sources for a lot of this information. I have put this series of web pages together only as a consolidator of information. The only goal is to assist the reader in understanding networking, routing, and switching better, and to possibly obtain a certification from Cisco as a CCNA. This collection is not published for my (or any) profit or gain.
Thank you for your understanding.
